Lake of the Prairies (Asessippi Provincial Park)

A man-made lake which crosses the provincial border into Saskatchewan, Lake of the Prairies was the result of the construction of the Shellmouth Dam, built in 1968 to control flooding upstream on the Assiniboine River. It fills a 67 km (42 mile) stretch of the Assiniboine River valley. Electrical campsites and fishing and houseboat rentals are available. You can also trek along the self-guiding Ancient Valley trail or enjoy the designated swimming area. The Trans Canada Trail follows the valley. Asessippi Ski Area and Winter Park is located just east of the lake.
